The proposal to build the world's largest hydro-power project on the Congo River is a century old. This article argues that the Grand Inga project could become the political, diplomatic, and economic driver to deepening integration between the Democratic Republic of the Congo and other African countries. The Inga delays were not without benefits. Twenty-first century sensibilities ensure revision of the proposed mega-project to minimize both ecological and social harm. While colonial-era projects were configured to maximize benefits to imperialist, settler, and corporate interests, independence and democratization are the prerequisites to facilitate the broadest possible distribution of the benefits of electrification. Since some of the countries involved have hybrid regimes, further democratization, and civil society lobbying, will be necessary to mitigate the downside of its ecological and social impacts.
